SIGRATHERM® Soft Felt

SIGARTHERM<sup>®</sup> Soft Felt and Rigid Felts

Flexible, oxidation resistant, efficient.

Soft felts are flexible insulation materials for high temperature applications in inert or vacuum atmosphere and consist purely of carbon fibers.

Stability of the felt is already defined in the first production step, the needling process and prevails throughout all following high temperature steps. Furthermore, soft felts can be used in energy storages like redox-flow batteries due to their controlled inner structure and electrical conductivity.

We market our soft felt for insulation application under the SIGRATHERM brand. Specially developed soft felt for energy storage applications, the so-called battery felts, are offered under the SIGRACELL® brand.
